Overview of Xerox Personal Computers

Xerox Personal Computers are comprised of four components:' display/processor, disk drives, keyboard, and optional printers. Both the 820-11 and 16/8 use the CP/M(!)-80 2.2 Operating System from Digital Research,lnc. Additionally, the 16/8 PC includes CP/M-86® 1.land MS '''DOS Version 2.0 as standard operating systems.

HARDWARE DESCRIPTION System Board The system board uses a Zilog Z80-A(!)-based microprocessor operating on a 4 megahertz clock with 64k RAM and 8k ROM. It is a single-board computer and uses a daughter board to interface with the disk drives. The 820-11 is equipped with three user-accessible 1/0 ports. Twa of the ports are located on the back of the display/processor; the third is located on the CPU board. On the back are the printer and the communications ports (both RS232C). The port inside the display is a dual parallel port (most printers and other devices that follow a sta'ndard Centronics 36-pin interface can be successfully attached).

The 16/8 has all of the above features as well as an Intel 80861~-based microprocessor operating with a 4.772 megahertz clock. The 8086 is equipped with 128k of RAM which is expandable to 256k total by addi ng a 128k daughter board to the 8086 board.

The 820-11 and 16/8 are capable of having up to 8k of read only memory (four 2k ROMs): the 820-11 has 6k 9f this 8k occupied; the 16/8 uses the full SK. The last 2k on the 16/S is used for decoding the position-encoded Low Profile Keyboard. The firmware contained in the ROM is capable of doing such things as executing a one-sector loader from disk; i.e., loading CP/M, emulating a terminal, operating in typewriter mode, etc. The monitor also has other commands that are useful for debugging hardware and software. The mother board also contains a speaker as well as an expansion slot (used by the 16/8 for the 8086 board). Ther~ are two types of daughter boards: one interfaces the display/processor to floppy disks and the other interfaces the display/processor to a rigid disk controller.

2 Introduction

Display The display/processor houses the video display, the CPU mother board, the disk drive daughter board, and the 8086 processor board if so configured. The video display is a standard 241ine by 80 characters. It uses a 7 x 10 dot matrix for each character in all text modes and displays white characters on a black screen. For graphics characters, it uses a 4 x 4 pixel resolution. The display attributes can be changed to display either in blink, highlightllowlight, inverse, or graphics characters.

Keyboards

Product Code #U03 Product Code HUOS Product Code #H69 Product Code #H70

The 820-11 and 16/8 use either a standard 96-character ASCII or Low Profile keyboards. Both keyboards include additional keys to the right of the keyboard, a 10-key numeric key pad and a set of keys for software control of the cursor. The low profile keyboard also includes 12 function keys that can be software-enabled and other keys such as Accept, Delete, Next, Previous, Home, and Undo ..

Printers 40 CPS Printer and 20 CPS Printer As their names imply, the printers have a printing speed of 20 and 40 characters per second (CPS) respectfully. Both printers have a wide range of print styles available. The 20 CPS Printer supports 10, 12, and 15 pitch as well as Proportional Spacing (PS), while the 40 CPS Printer supports either metal or plasticprintwheels in 10, 12, 1 S, and PS. More detailed information on these printers can be found in the Printer section under Peripherals.

The standard RS232C printer connector and dual parallel port are available to·interface with many types of serial and parallel printers.

FUNCTIONAL DESCRIPTION

Product Code # 080 Product Code # UOl

The 820-11 and 16/8 systems are a collection of four components working in unison -- the display, keyboard, disk drives, and printer. The computer itself is housed in the display.

System Monitor· ROM The system monitor contained withiri the 8k ROM controls the essential functions of initializing and controlling all system input/output resources, and also provides a number of monitor commands that cao be used to assist in, programming. .

Ports Three ports are standard on the 820-11 and 16/8: two serial ports located at the back of the display unit and an additional dual parallel port inside the di'splay unit. These allow printers, communication devices, and other peripheral equipment to be interfaced with the system.

Operating Systems The 820-11 uses Digital Research's 2.2 CP/M-80 Operating System. The 16/8 can use Digital Research's 2.2 CP/M Operating System, as well as their CP/M-86 1.1 Operating System and Microsoft's MS-DOS 2.0 Operating System. These operating systems provide the user with a general environment for program construction, storage, and editing, along with assembly and program checkout facilities.

Introduction

CP/M-80 operating system software as implemented on the 820-11 and the 1618 is logically divided into four parts:

ROSR BIOS BOOS CCP

ROM Operating System Routines (hardware dependent) Basic 1/0 System (hardware dependent)-Basic Disk Operating System* Console Command Processor*

*Oisk resident portions of CP/M-80

ROSR provides code in ROM that can be executed without th~\ presence of the CPIM system disk and provides the primitive operations necessary to access the disk drives and to interface with peripherals.

BIOS provides the interface between BOOS and ROSR.

BOOS provides disk management by controlling one or more disk drives containing independent file directories.

CCP provides symbolic interface between the user's console and the remainder of the CPIM system.

HARDWARE INTERFACE The 820-11 and 16/8 are equipped with six input/output connectors. Four are on the back of the display unit and two are inside the display.

Disk Drive Used for connection of either the 8" or the 5t" Dual Floppy Drives, or the 8" Rigid Disk Drive. This is determined by the type of disk daughter board installed in the display processor.

Keyboard Used for connection of either the ASCII or Low Profile keyboard.

Printer A serial printer can be attached to this RS-232-C connector.

COMM COMM is a second RS-232-C connector and can be used for a modem.

5

Parallel Port A dual parallel port inside the display cabinet is also provided.

Expansion Slot The expansion slot inside the display cabinet provides all of the Z80-A microprocessor control signals for connection to custom devices for future expansion. This slot is used for the 8086 co-processor if you have a 16/8.

CP/M-SO

The CP/M-80 2.2-C disk for the 820-11 contains the standard Digital Research software development and checkout programs. Xerox issues additional utility programs that are unique to the 820-11. A description of each program is listed below:

which can be read and executed by the 820-11. The Dynamic Debugging Tool is used to debug a Z80-A assembly language program. Allows binary command files that are not displayed on screen to be displayed showing the hexadecimal value for each byte. A line-oriented screen editor. Reads an .REL file created with the Macro-80 Assembler Program and outputs a command file. Reads a .HEX file and creates a command file. Converts a program written in Assembly Language to a relocatable (.REL) file and (optionally) a printer listing file (.PRN). Lets you modify and move the CP/M system image to allocate a specific lesser memory size. Allows you to selectively copy a file or files from one disk to another or on the same disk. The status utility is a frequently-used transient command for all system housekeeping; i.e., checking the amount of space available on a disk. Used to submit afile of commands for batch processing.

CONFIGUR.COM

IntrArI"rtinn

Used to generate a CP/M-80 system image and copy the operating system to another disk. Same as Submit.com, but has the facility to include line input to programs as well as the console command processor.

A multi-option utility that allows you to archive and retrieve files, delete files, list directories.of any drive, and to verify data integrity of a floppy or rigid disk. Using Configur.com, you can select seven different options: 1. Record Restart Command - lets you enter a one

line command which will automatkally load a program .. For example, you could enter DIR a~ the restart command and every time you boot the system, it will automatically display the directory for you. Or you could enter the name of your application software package and it would automatically load that application package for you. This command is recorded on the disk and you can have a·different one for each disk.

2. Select Printer Port Options - allows you to determine printer protocol. This option allows configuration for alternate printers without modifying the BIOS.

3. Select Communications Port Options - a convenient method for setting up the communications port on the 820-11 or 16/8; that is, baud rate, protocol, stop bits,.etc.

4. Select I/O Device Assignments - lets you select alternative inputJoutput device assignments; i.e., set up the system so that everything displayed on the screen automatically prints on the printer.

5. Select Keyboard Data Format -lets you choose 7-bit or 8-bit mode for the keyboard.

6. Select Screen Attributes - includes blink, inverse video, highlightJlowlight, and graphics modes.

Turns offthe<CTRL> + <ESC> feature to enable use of <CTRL> + <ESC> for other purposes; for example, setting margins and tabs on a 40 CPS printer uSeS a <CTRL> + <ESC> sequence. A convenient method to temporarily change communication and printer port options in RAM. A utility that allows the user to swap drive names. For example, "A" and "E" for a rigid disk drive. By designating an alternate drive as the" A" drive, you can load software directly from that drive. Many CP/M-SO application packages have been written to be executed from the "A" disk drive only. Using Swap. com allows you to place your application software on any disk drive and load. Displays the time and date on screen. Since there is no battery backup, however, you must re-enter the time and date each time you reload the system. This utility lists the logical and physical names for each disk drive, as well as the density, number of

FUNCTIONAL DESCRIPTION, XEROX DISPLAY

The display has the following functional characteristics:

• 241ine display • 80 characters per line • 7x 1 0 dot matrix per character • White characters on black • Software-selectible character attributes

• Brightness adjust

DISPLA V CONTROLLER

The Display Controller is based 'on displaying characters within a 7x10 cell (7 dots horizontally by 10 scan lines vertically). To guarantee spaces between characters, one dot on each side of the cell is blanked by hardware. Also, to guarantee spaces between character lines, the top two scan lines are blanked by hardware. This gives an actual active character size of 5 dots horizontally by 8 scan lines vertically.

For Business Graphic~, the hardware is configured to eliminate the automatic blanking and allow continuous lines both horizontally and vertically. However, the Display Controller is still based on displaying a character within a 7 x 10 cell. The controller design and available refresh memory allows one byte per character. The maximum number of unique characters that can be defined by any 8 bits is 256. Since the standard text font set contains 128 characters, the Ii mit on unique characters for graphics that can be displayed together with text is 128.

The character set for Business Graphics divides the cell intq blocks of 4 dots horizontally by 4 scan lines vertically. Since the total number of scan lines per character is 10, the character set actually consists of two sub-sets of 4-4-2 and 2-4-4.

Each subset divides the cell into 6 parts requiring 64 possible combinations or unique characters. Therefore, the total number of unique characters forthe complete grap/:1ics set is 128. With this

16 Miscellaneous Hardware Information

character set, any combination of adjacent 4 x 4 blocks can be chosen. Also, at the character cell boundary, the 4 x 4 blocks can be set vertically by 2 scan lines. Since the total number of horizontal dots per cell is 7, there will be an overlap of one horizontal dot in the center of the cell for diagonal blocks within the cell.

It should be also noted that for the standard text font containing 128 unique characters defined by 7 bits, the eighth bit is used to set the attribute function. For Business Graphics. since both text characters and graphic characters can be displayed simultaneously, it requires all 8 bits to define the character. Consequently, display attributes are not available in graphics mode.

the address bus holds a valid I/O address for an 1/0 read or write operation. This signal is also generated with a "/M1" signal when an interrupt is being acknowledged to indicate that an interrupt response vector can be placed on the data bus. Interrupt Acknowledge operations occur during "/M1" time, while 1/0 operations never occur during "/M1" time .. Halt (Output, active low) signal indicates that the C;:PU has executed a Halt Software instruction and is awaiting either a non-maskable or maskable interrupt before operation can resume. Memory' Request (Tri-state, output, active low) signal indicates that the address bus holds a valid address for a memory read or memory write operation. Refresh (Tri-state, output, active low) indicates that the lower 7 bits of the address contain a refresh address for dynamic memories and the "/MEMRQ" signal should be used to perform a refresh cycle for all dynamic RAMs in the system. During the refresh cycle" AT' is a"logic zero and the upper 8 bits of the address bus contain the "I" register.

Mic;cp.llaneous Hardware Information

IIORQ 6 I/O Request IIORQ indicates that the lower half of the address bus holds a valid 1/0 address for an 1/0 read or write operation. IIORQ is also generated concurrently with 1M 1 during an interrupt ackn~wledge cycle to indicate that an interrupt response vector can be placed on the data bus.

IWR 8 Write Controls output on the data registers 00-07.

IBUSAC~ 10 Bus IBUSACk indicates to the Acknowledge requesting device that the CPU

address bus, data bus, and control signals IMREQ, IIORQ, IRO, IWR have entered the high impedance states. The external circuitry can now control these lines.

IM1 12 Machine 1M 1, together with fM REQ Cycle 1 indicates that the current

machine cycle is the op-code fetch cycle of an instruction execution. 1M 1, together with fIORQ, indicates an interrupt acknowledge cycle.

IBUSREQ 32 Bus Request IBUSREQ has the highest priority and is always recognized at the end of the current machine cycle. IBUSREQ forces the CPU address bus, data bus, and control signals IMREQ, IIORQ, IRD, and IWR to go to a high impedance state so that other devices can control these lines.

IBUSAKl 34 Bus IBUSAK 1 is daisy-chained Bus Acknowledge Acknowledge output which

indicates to the reqw~sting device that the CPU address bus, data bus, and control signals IMREQ, JlORQ, IRO, IWR have entered the high impedance states. The

Notes


Theory of Operation

The display processor houses the system board, disk drive daughter board, the CRT, the power supply, and one bus expansion slot.

The system board has the following:

CPU

• Central Processing Unit (CPU) • 6 to 8k of Read Only Memory (ROM) • 64k of Random Access (ReadIWrite) Memory (RAM) • Counter Timer Circuit (CTC) • Serial Input/Output Controller (SIO) • Parallel Input/Output Controller (PIO), • Two RS-232-C Serial 1/0 Ports • Dual 8-bit Parallel Ports • CRT Controller and CRT Refresh Memory • Speaker • Disk Drive Daughter Board Connector • Bus Expansion Connector

• 8086 Co-processor (1618 system) • Parallel Keyboard Interface

i ,I

The CPU is a Zilog Z80-A operating with a clock rate of 4 Mhz. It is initialized to use Interrupt Mode 2 by the ROSR monitor at power on. The Z80-A also provides refresh to the 64k of dynamic memory on the system board. Therefore, the I and R registers should not be altered by an application program.

ROM and RAM Memory The System Board has two banks, of memory. Bank 1 has 64k of RAM. Bank 0 has up to 8K of ROM.

When power is turned on or RESET is pressed, the Monitor, ROMICRT RAM (Bank,o), is enabled by the hardware and the contents of the monitor ROM are moved by the CPU to the program memory starting at location fOOOH. When the move is complete, the CPU transfers control to

A1

location FOOOH and RAM (Bank 1) is enabled. Bank 0 is also enabled when a character is sent to the screen.

6-8k ROM The CPU board has provisions for 4-2k x 8 Read Only Memory devices. The first 3 (U33, U34 & U35) store the firmware for the ROSR monitor. The fourth (U36) provides translation tables and related firmware for the position-encoded low profile keyboard.

64k RAM The 64k byte (65536 x 8) RAM provides space for a portion of the ROSR monitor (upper 4k FOOOh - FFFFh), and 60k (OOOOh - EFFFh) is free for programs to execute in such as an operating system and an application program. This RAM is dynamic and refresh is provided by the Z80-A CPU.

Counter Timer Circuit (eTC) The CTC has four independently-programmable counter/timer channels, each with a readable downcounter and a selectable 16 or 256 prescaler. Downcounters are reloaded automatically at zero. Each channel isprogrammed with two bytes. Once started, the CTC counts down, reload~ its time constant automatically, and resumes counting. Internally, the CTC generates a unique vector for each channel.

SeriallnputlOutput Controller (S10) The Serial,l/O Controller has two independent, full-duplex channels with separate control and status lines for modems or other devices. Data rates are from 50 to 19,200 bits/second. Channel A (modem) supports both Asynchronous and Synchronous protocols. Channel B (printer) is dedicated to Asynchronous. The receiver is quadruple-buffered and the transmitter is double-buffered. The controller also supports daisy-chain interrupt vectoring for interrupts without external logic.

Serial I/O Ports The 820-11 CPU board contains a Z80-A SIO that provides two useraccessible serial ports to the 25-pin printer and modem connectors on the rear of the display processor. The Communications port is capable of operating in synchronous or asynschronous modes, while'the Printer port is only cap~ble of operating asynchronously. On an Etch 2 CPU, there is a 30-pin connector. Selection of synchronous or asynchronous mode is under program control as opposed to the Etch 1 CPU (with a 40-pin

.47 Theorv of Operation

connector) where a physical change is required to make the sync or async selection.

Parallel Input/Output Controller (PIO) There is a System and a General Purpose Parallel 110 Controller which provides direct interface between the CPU and the peripheral devices. Each controller has two 8-bit 110 ports. The System PIO is dedicated for keyboard input, memory bank and CRT font selection, and floppy disk drive and side selection. The General Purpose PIO provides the user with a dual 8-bit parallel 110 port for interfacing with peripherals.

Parallel Port The Z80-A General Purpose PIO is accessible on the main CPU board on connector J8. This PIO is programmed by the ROSR monitor at power-on to provide a parallel Centronics-compatible interface for a parallel printer. A transceiver is physically located between the Z80-A PIO and the J8 connector. Jumpers must be installed on option connector J 11 to select whether the transceiver will transmit or receive data. See also page 24.

CRT Controller The CPU board contains the 2k of refresh RAM where the characters that are to be displayed on the screen are stored. It also has the necessary electronics to provide the control signals (sync and video) to the CRT monitor. The CPU board has two character font ROMs; each font ROM contains two character sets.

US7 Normal white on black font Reverse video font

US8 Normal whi~e on black font Graphic chqracter font

I

The CRT driver in the ROSR monitor translates character-level escape sequences into commands as to which of the font ROMs to select and which of the two fonts inside the selected font ROM to select. Basically, characters that are stored in the CRT's refresh memory address the selected font ROM; the font ROM provides dot information to the video input of the CRT so the character can be displayed. .

ThoarH o-fI'Ioor"ltinn ... 4~

The characters on the CRT can have one of the following attributes:

Blink Inverse video Graphics Low intensity

The most significant bit of the character stored in the CRT's refresh memory determines if the character is to be displayed with its attribute enabled.

The ROSRmonitor provides a character-oriented command format for controlling the screen and font ROM selection. It is recommended that programs use this method to control the CRT and its attributes.

Theory of Operation

CRT RAM Memory Allocation The CRT RAM occupies 3000H - 3fFFH in bank 0 (System Bank). Each 80-character line on the CRT is allocated 128 bytes in the CRT RAM. Listed below are the starting and ending addresses for each of the 24 rows in the CRT RAM. The example (at the bottom) shows some character locations in CRT memory. (Assumes scroll register = 23)

Row Starting Address Ending Address

0 3000H 304FH 1 3080H 30CFH 2 3100H 314FH 3 3,180H 31CFH 4 3200H 324FH 5 3280H 32CFH 6 3300H 334FH 7 3380H 33CFH 8 3400H 344FH 9 3480H 34CFH

Scroll Register To eliminate the delay associated with software scrolling, hardware scrolling is employed. Writing into the scroll register (Port 14h) adds an offset to the line address developed by the line counter. Fqr instance, with an offset of zero (scroll register = 0), the data at locatjon 3000H (in the CRT refresh memory) will be displayed on the bottom row of the . display. If the offset is 23, the data at location 3000H will be displayed on the top row of the screen. The scroll register is loaded from AS to A 15 rather than 00 to 07. Therefore, the scroll value must be in the B register' if an indirect OUT instruction is used.

46 Theory of Operation

Speaker The 820-11 and 16/8 have an audio speaker connected to two I/O ports (28h and 29h). Outputting to one I/O port causes the speak~'!r cone to be pushed out; outputting to the other I/O port pulls in the speaker cone. The actual value output to these ports has no significance. To generate a beep, the application program can simply send an ASCII Bell character to the CRT. To generate a tone other than the standard bell character, the program must move the speaker cone in and out at the desired frequency.

Disk Drive Daughter Board The disk drive connector on the rear is a "dual personality" connector, depending on which disk drive daughter board is installed on the mother board. Presently; there are two types of disk interface:

Shugart SASI interface controller suitable for interfacing to a SA 14030 Rigid Disk Controller.

Floppy-only interface suitable for interfacing to Shugart SA800/SA400USA8S0/SA450 dual daisy-chained disk configurations.

The ROSR monitor detects which daughter board is installed at power-on and selects the appropriate physical disk driver firmware to process physical disk drive requests.

Caution: If a rigid disk drive unit (U07, U08) is connected to a floppy display/processor (U03JH69, U04), the rigid controller PWB will be destroyed when power is switched on. The rigid disk drive unit must be connected only to a rigid display/processor (U05/H70, U06). Connecting a floppy disk drive unit (929IT66/973/Fl 0, E41/E44/E42/E89) to a rigid display/processor (UOS/H70, U06) may c'ause the processor PWB to fail. Before connecting any disk drive unit to a display/processor, check that the configuration of the display/processor is compatible with the disk drive unit. The configuration can be determined in one of two ways. (1) Check the product code of the display/processor. The product code is the first three digits of the serial number, located on the underside of the display processor. (2) Verify that the proper drive interface PWB is installed by checking the part number. .

47

System Bus The System Bus contains an 8-bit Data Bus (Tri-state, Input/Output) bidirectional Data exchange with memory and I/O devices. It has a 16-bit Address Bus to address up to 64k of memory for 1/0 devices data exchange.

Keyboard Interface The keyboard FIFO (Etch 2 CPU only) has space for 16 (decimal) entries. Associated with the keyboard FIFO are input and output position pointers and a count of the number of entries curr'ently in the FIFO.

The available memory pointers provide the addresses bounding the available unused RAM in the memory reserved for system use. Although these pointers are a supported feature, there is no guaranteed available memory size.

There are twotables used to disk map a logical disk to its physical driver; The first table, Seltab, associates a logical disk number with a physical disk number; The second table, Drvtab, identi'fies which physical disk driver is appropriate to use with the selected physical disk.

The physical driver command block is a collection of all information necessary for the disk system to perform the requested disk activity.

The timer and clock variables are a collection of locations used for main.taining the one second timer and the time-of-day clock and calendar; The console command line buffer immediately follows these variables.

1.0 INTRODUCTION

The SA 14030 Controller consists of a micrprocessor based controller with on-board data separator logic and is able to control a maximum of four drives. The drives can be any combination of Shugart SA 1000 fixed disk drives. SA800 floppy disk drives. or SA850 floppy disk drives. The floppy disk track formats are compatible with IBM 10/20 track formats. The SA 14030 can be mounted on the SAl 000 drive.

Commands are issued to the controller over a bidirectional bus connected to the host computer. The data separator/"serdes" logic serializes bytes and converts to FM/MFM data. and deserializes FM/MFM data into 8-bit bytes.

Due to the microprogrammed approach utilized in the controller. limited diagnostic capabilities are implemented. This methodology increases fault isolation efficiency and reduces system down time. Error jetection and correction will tolerate media imperfections up to 4-bit burs't errors.

:'-lOTE: This device utilizes neaative logic (i.e .. OV = logical 1)

FIXED SECTOR SIZE

In multiple drive configurations the host can issue seeks to different drives without waiting for the fi rst drive to complete its seek.

A seek command is implied in every data transfer command (READ. WRITE CHECK. etc.). If the heads are not positioned over the correct cylinder. a seek is initiated and a cylinder verification is performed after the seek completes.

Three classes of fault detection are provided for fault diagnosis: 1) Disk related faults. 2) Controller related faults. 3) Host comma~d or 110 timing faults. Fault detection is available from the interface as a status message and is also visibly displayed on a row of status LED's on the controller PCB. .

If during a multi-block data transfer the end of a track is reached. the controller automatically switches to the next track. If the end of a cylinder is reached. the controller issues a seek and resumes the transfer.

. -If a data error IS detected during a disk data transfer. the controller indicates whether or not it is correctable. If correctable, it can be automatically corrected. (This applies to the SAl 000 only. CRC error detection is used on floopy disc drives.)

Logl~~. Unit Number (LUN's) are independent of physical port numbers. All accesses specify LUN's.

A sector buffer is provided on the controller to eliminate the possibility of data overruns during a data transfer.

A bidirectional bus between the controller and host provides a simple. yet efficient communication path. In addition. a high level command set permits effective command initiation.

Sector interleaving is programmable with up to a 16 way interleave.

The 8 data bits on the interface bus can have odd parity. Depending on user preference. parity can be disabled.

The sector size is fixed at 256 bytes of data for the SA 1000.

3.1 CABLE TERMINATION

The last physical drive at the end of J1 (50 pin) cable must be properly terminated. Termination networks are provided on the drives (refer to SA 1000. SA800 or SA850 OEM manuals for location of termination networks). Termination networks must be removed from all drives except the last drive on the cable to avoid multiple termination.

NOTE: If a combination of fixed and floppy drive are used., the last drive at the end of the control cable must be an SA 1000.

4!O HOST CPU INTERFACE

The SA 1400 series controller interface is a general purpose 8 bit parallel D MA.

The Host CPU is interfaced to the controller via connector J6t J6 is a 50 pin socket type connector. The· recommended mating connector'for J6 is a 3M Scotch flex ribbon connector PIN 3425-3000. The J6 interface cable should not exceed 20 feet (6 meters).

4.1 HOST CPU ELECTRICAL INTERFACE

All Host CPU interface signals are negative true. The signals are "Asserted" at 0 VDC to 0.4 VDC. The signals are "Deasserted" or inactive at 2.5 VDC to 5.25 VDC.

4.1.1 HOST CPU INTERFACE TERMINATION

All Host CPU interface timing lines are terminated with a 220/330 ohm network. The Host CPU adapter should be terminated in a similar fashion (see Figure 4).

The devices driving the controller inputs should be open collector devices capable of sinking at least 48 milliamps to a voltage level of less than 0.5 VDC (7438 or equivalent). ' ,

Jhe devices receiving the controller outputs s'hould be of the SCHMITT trigger type to improve the noise margin (74LS240. 74LS14. or equivalent). The Host adaptor should not load the bus with more than' standard TTL input load per line.

4.2 SA14030 HOST BUS

4.2.1 THEORY OF OPERATIONS

Disk commands are issued to the SA 14030 via the host bus following a defined protocol. The host initiates a command sequence by selecting the controller on the bus. If the controller is not busy, it requests command bytes from the host for task execution. (Command structure is described in 4.5). Depending on the type of command. the controller wilrrequest either 6 or 10 bytes. Upon reception of the last command byte, the con-troller begins execution of the command. .

258 SA 1403D Controller Reprint

For the data transfer commands. a check is performed on the disk address and status flagged if It exceeds tne drive limits. The data IS stored In a sector buffer before transfer to the host or disk drive. This buffer eliminates any possibility of data overruns between the host and the disk.

Upon completion of the command. the controller will send completion status to the host. Further delineation of the completion status may be requested by issuing the appropriate sense commands.

Odd parity is' generated by the SA 14030 for all information that it puts on the I/O bus. If ena,bled. the SA 14030 checks all information that it receives for odd parity.

4.3 SIGNAL DEFINITION

Unidirectional Signals Oriven By Controller

110

c/o

BUSY

MSG

Input/Output. When asserted. the data on the bus is driven by the controller; when deasserted. the data on the bus is driven by the host adapter. The host adapter will use this line to enable its drivers onto the data bus.

Control/Data. When asserted the data transmitted across the bus will be the command or status bytes; when deasserted the data will be the disk data bytes.

This bit is asserted as a tesponse to the SEL line from the host adapter and to indicate that the host bus is currently in use.

Message. When asserted indicates that the command is completed and status has been transferred. The assertion of this bit is always followed with the assertion cf I/O, and the assertion of REO, to cause a message byte transfer.

REO Request. This bit operates in conjunction with 1/0. C/O, & MSG. When asserted and 1/0 is asserted. REO will mean that the data on the host bus is driven by the contr.oller. When asserted' and 1/0 is deasserted, REO will mean that the data is driven by. the host adaptor (HI A).

1/0 C/O MSG Meaning

d a d Get command from H/A d d 'd Get data from H/A a d d Send data to H/A a a d Send status byte to H/A a a a Command done to H/A

TABLE 2.

a = asserted. d =. deasserted, H/A = host adaptor

4.4 UNIDIRECTIONAL SIGNALS DRIVEN BY HOST ADAPTOR

ACK Acknowledge. This bit is asserted as a response to REO from the controller. The timing requirements on this-signal with respect to thF' data is cescribed in REQuest section. ACK must be returned for each REQ assertinn

SA 1403D Controller Reprint

/.

259

RST Reset. Assertion by the Host causes the controller to cease all 9perations and return to an idle condition. This signal is normally used during a power up sequence. A reset during a write operation would cause incorrect data to be writter on the selected disk. The controller may take a maximum of 2 seconds to respond to the select sequence following deassertion of the RESET line.

SEL Select. When asserted indicates the beginning of the· command transaction. The H/A asserts SEL to gain the attention of the controller. Data bit zero on the host bus must also be asserted during SEL time to select the controller address. The controller will return BUSY within approximately 1tLs.

4.4.1 DATA BUS BITS 0·7 (DB)

These bidirectional data lines are used to transfer 8 bit parallel data to/from the Host adaptor. Bit 7 is most signifant bit. NOTE: All ifF lines utilize negative logic.

4.4.2 PARITY BIT

This bit is asserted to maintain odd parity on all data and status information transfered to the Host. If enabled, the controller will test for odd parity on all command and data information transfered to the controller (see section 9:1).

4.5 HOST INTERFACE PROTOCOL

There are 4 sequences required to initiate and complete a command to the SA 14030 series controller:

1) Controller Selection Sequence

2) Command Transfer Squence

3) Data Transfer Sequence

4) Status and Message Transfer Sequence

4.5.1 CONTROLLER SELECTION SEQUENCE

In order to gain the attention of the controller it is necessary to perform a selection sequence. Refer also to Figure 6.

The Host must first test BSY to determine if the controller is available. If BSY is deasserted. the Host will assert data bit 0 (cortroller 10) and then assert SEL. The controller will then respond by asserting BSY. At this point the Host must deassert SEL and data bit O. 110 will remain deasserted throughout the selection sequence.

4.5.2 COMMAND TRANSFER SEQUENCE

Following the selection sequence the controller will assert REO (see Figure 6). The Host will then place the first byte of the command descriptor block (see section 5.0) on the data bus. The Host will then assert ACK (if ACK is not asserted within 256 microseconds after the assertion of REO. the controller will abort the com· mand transfer sequence and attempt to transfer a status byte). The controller will respond by reading the byte on the data bus and then deasserting REO. The Host then must deassert ACK to begin the next I REO/ACK handshake. This handshake must be completed to assure that all command and data bytes are .. transferred.

4.5.3 DATA TRANSFER SEQUENCE

Following the command transfer sequence, the controller will respond on one of four ways:

1) Begin seeking the drive.

2) Begin accepting write data from the Host.

3) Begin transferring read data to the Host.

4) Return status to the Host. .

If the command sent to the controller involves a data transfer (see Figure 7), the controller will deassert the C/O line to indicate a data transfer. If the data transfer is from the Host to the controller (write data) the 110 line will be deasserted. If the data transfer is from the controller to the Host (read data) the I/O line will be asserted. The controller will then set the REO line to request a byte transfer. The Host will respond by transferring a byte across the data bus and then asserting ACK (if ACK is not asserted within 256 microseconds after the assertion of REO, the controller will abort the data transfer sequence and attempt to transfer a status byte - see section 4.5.4). The Host will then deassert ACK and wait for the next assertion of REO. This handshake continues until all data has been transferred

4.5.4 STATUS AND MESSAGE TRANSFER SEQUENCE

Following a command transfer or data transfer, the controller will initiate a status byte and completion message transfer.

When a status byte transfer is required, the controller will assert C/D and 110 (see Figure 8). The controller will then assert REO. The Host must then read the status byte on the data bus and then assert ACK (if ACK is not asserted within 256 microseconds after the assertion of REO, REO will be deasserted. REO will then be asserted again).The controller will then deassert REO. The host will then deassert ACK.

.. Following the s~atus byte transfer, a completion message byte of all zero's will be transfered to indicate operation complete. The controller will assert the MSG line (along with 1/0 and C/O) and then assert REO. The Host may read the completion message byte on the data bus and assert ACK (if ACK is not asserted within 256 microseconds, the controller will deassert the MSG line and attempt to transfer a status byte). The controller will respond by deasserting REO. The Host will then deassert ACK. At this pOint BSY and all other controller 1/0 lines will be deasserted and the controller will return to an IDLE LOOP awaiting the nexiselection sequence.

FIGURES. STATUS AND COMPLETION SEQUENCE TIMING

5.0 CONTROLLER COMMAND DESCRIPTOR BLOCK

Follow(ng the controller 'selection sequence the controller will request a command descriptor block (CDS)' which, depending on the class of command, may be either 6 or 10 bytes in length. The first byte of the CDS co~tains ~he command class and the command operation code. The re!!'Jalning b¥tes. specify the drive. logical unit number (LUN), logical sector address, number of ~ectors to be transfered or a destination device (Copy Command), and a control field byte.

Commands are categorized into four classes as indicated:

Class 0 Class 1 Class 2-5,7 Class 6

- Utility, Data Transfer and Status Commands - Disk Copy Commands - Reserved - Floppy Disk Track Format Selection

The command descriptor blocks in Command Class 0 and 6 are 6 bytes'long, and those in CI9-sS 1 are 10 bytes long.

The controller will check all incoming command descriptor blocks for validity ana will also check (if enabled) all COB's and data for odd parity (see section 9.1). A parjty error will cause an immediate halt of the command or data transfer. This will not cause incorrect data to be written because the write does not occur until the sector buffer has been filled. An error in the command structure will cause a status byte transfer to occur' upon completion of the CDS transfer.

5.3 STATUS FORMAT

5.3.1 Completion Status Byte Format

At the normal termination of a command or following a fatal error. the controller will cause a status byte to be transferred from the controller to the Host. Bit 0, the least significant bit of the status byte, will be set equal to 1 if the controller detects a parity error during a command o·r data transfer to the controller. Bit 1 will be set = 1 if the controller detects an error condition. Bits 5 and 6 represent the LUN of the device where the error occured. If no error occurs, bit a -4 will be set equal to O. .

Following the transfer of the status byte, the MSG line will be asserted to indicate a completion message. At this time the message consists of a single byte transfer with all bits set = O.

Prior to an error condition the controller, unless diabled (see section 5.2.1 Control Field), will retry 3 times before posting the error.

5.5 LOGICAL ADDRESS

The logical address is computed as follows:

Logical adr = (CYADR * HDCYL + ~DADR) * SETRK + (SEADR)

Where: CYADR = cylinder address HDADR = head address SEADR = sector address HDCYL = number of heads per cylinder SETRK = number of sectors per track

Bit 0 at Logical adr 0 = the least significant bit. Bit 4 of Logical adr 2 = the most significant bit.

Note: All addresses begin with 00.


6.0 SECTOR INTERLEAVE CODES

In order to tailor host system data transfer speed to the disk rotational speed, sector interleaving is offered. Sixteen interleave codes are offered numbered 1 to 16. Not all interleave codes will result in optimum sector interleave, therefore the interleave should be chosen carefully. In order to maintain IBM floppy disk compatibility in interleave code of 1 should be used. This will result in a non-interleave condition.

6.1 SELECTING THE RIGID DISK INTERLEAVE CODE

The interleave code given during the format command is used to calculate the logical sector number for the rigid disk as follows: Logical Sector = (Physical Sector x Interleave code) (mod 32). Note: when the logical sector number exceeds 31 the next logical sector is the lowest available physical sector. This does not always create a true modulo function.

7.0 DIAGNOSTIC PHILSOPHY

7.1 BOARD RESIDENT MICRODIAGNOSTIC

Fault Isolation Microdiagnostic (Optional) The controller can be further checked out off-line by initiating explicit microdiagnostic routines via optional firmware diagnostic sets. The routines are initiated by a ·set of control switches. Errors will be dislayed in a set of LED's. Each microdiagnostic checks the funtionality of a particular section of the controller and is able to isolate failures in the following major categories: .

ALU Registers Sector Buffer ECC Logics

F~ult-isolation .techniques can be concentrated on the failing section.


8.0 STATUS LED ERROR INTERPRETATION

Drive/controlier error conditions are displayed on the 8 LED display lights provided near the J1 0 DC power connector (see Figures 11). The following list of hexadecimal numbered error codes describe error meanings. Note that these error codes do not necessarily match the request sense block error codes. LED number 7 is the MSB.

01 No Index Detected

02 No Track Zero Detected

03 Illegal Logical Sector Address - beyond maximum sectors available for type of drive

04 Drive Not Selected (SA10000nly)

OS No Seek Complete Detected

06 10 Address Mark Not found (unformatted)

07 . Data Address Mark Not found

08 Seek Error - R/W head not positioned on correct track

09 Record Not found - found correct cylinder and head but not sector

OB DMA Timeout Error - no Host acknowledge within 256ILsec after request.

OC Invalid Command Received from Host

00 Incorrect Data Address Mark

OE Incorrect 10 Address Mark

OF Incorrect Cylinder Address

10 Incorrect Sector Address

11 Incorrect Head Address

12 Uncorrectable Data Field ECC or CRC error

1 3 Correctable Data Field ECC error

, 1 4 0 rive Not Ready

15 Write Fault (SA 1000 and SA4000/4100 only)

16 Spare

17 Write Protected (SA800/8S0 only)

18 RAM Diagnostic Error

19-1 F Spare

20 Parity Error

21 Bad Sector found - a sector within a track that has been flagged bad has been found.

22 Invalid function for this drive type.


9.0 CONTROLLER OPTION SELECTION

9.1 PARITY SELECT JUMPERS

Odd parity may be used by the Host system for data integrity verification. The controller will always output odd parity to the Host system.

Odd parity checking by the controller may be allowed or inhibited by moving a 3 position jumper plug at W2 located near the J6 Host connector (see Figure 11). With jumper at position A + B the controller will test for odd parity on all data input to the controller. With jumper at positon B + C the controller will not check for parity (normally shipped in A + B).

10.0 TRACK FORMAT DESCRIPTION

10.1 26 SECTOR FORMAT

The 26 sector format is an IBM compatible format which employes FM single density encoding on all tracks of the single density format (IBM 3740 compatible) and on track O. side 0 of the double density format. This format yields ~6 sectors of 128 bytes per sector.

The remainder of the tracks on the double density formats are encoded with MFM double density which yields 26 sectors of 256 bytes per sector (IBM system 34 compatible). Figure 9 shows the two type of encoding utilized.

CP/M-SO 2.2 BIOS Programming Considf::rations

BIOS provides the operations necessary to access the disk drives and to interface with peripherals. The user interface with the'BIOS is through a series of Entry Points. These entry points are II Jump Vectors". Each jump address corresponds to a particular subroutine which performs a specific function. The Base ( + B for the jump vectors) depends on the size of RAM memory.

How To Make Monitor Calls from Basic Several of the monitor function calls return the value in the HL register if the H register equals 0, or return the value at the address pointed to by the HL register if the H register is not zero. This convention allows Microsoft Basic Users to access these functions directly. The examples listed in this section demonstrate this feature of the ROSR ROM.

Bank Switchin.g

• The Bank control switch is bit 7 of port lC. Bit 7 = 0 = Bank 1 (RAM) Bit 7 = 1 = Bpnk 0 (ROM) .

• Change bit 7 only: Bits 0 through 6 should be maintained.

• Bank 0 and 1 are mutually exclusive; data movement to or from one bank will not affect the other.

• When bank switching, the driver code must be executed at COOOh or above; the upper 16K (COOOh-FFFFh) is common memory to both banks.

Rom code placement macros.

The Cownon Segment holds the non-resident (banked) portion of the monitor. This segment is not copied to ram.

The Data Segment holds the resident portion of the monitor. It is moved to ram at location MONITR during initialization.

The Coele Segment holds the various Transient Commands. Each command is loaded from the ROM to the TPA when It Is executed.

The fol lowing macros keep it all straight.

Title Banked Physical Driver

Banked Physical Driver

Copyright (C) 19B2, Balcones -Computer Corporation

Transferred to Public Domain - (PO) 19B3

After executing this program by entering BANK x:(where x is any valid CPIM (Jisk drive A-P). The BANK program wi II load a physical disk driver into memory. This phy!;ical driver is executed when drive x: is accessed by CP/M. This particular disk driver will map normal CP/M files onto the address space of the alternate memory bank (bank 0) in the 820-11.

This utility demonstrates the flexibility of the logical to physical diSk mapping in the B20-11. The BANK program moves the physical disk driver up to high memory. It then updates the entry for drive x: in the logical to physical disk drive mapping table telling the system to use physical disk driver #3 when CPIM requests service from drive x:.

The execution address of the BANK driver is then placed in entry #3 of the physical disk driver address table.

If BANK is executed by entering: A>BANK P:

Then doing a A>DIR P: would display tile following directory:

BOOT .ROM OPTION .ROM SCREEN .MEM

Entering: A>STAT P:*.* will display the following:

Recs 64

256 16 24

Bytes 12k 32k

2k 4k

Ext Acc 1 RIO 1 R/W

R/W R/W

Bytes Remaining On P:

P:BOOT.ROM P;EXPAND.RAM P: OPTION. ROM P:SCREEN.MEM Ok

EXPAND .RAM

The files map to the fol lowing memory addresses in bank 0:

BOOT.ROM EXPAND. RAM OPTION.ROM SCREEN.MEM

0000h-2fffh 400otl-bfffh 17ffh-1 fffh 3000h-3bffh

The BANK program can also be a very useful tool in that after it has been executed a high level language program can access it-ems in ttle alternato memory bank as disk files on drive Xl

Of particular interest is the file SCREEN.MEM, notice that it is 24 records long. Each record (12B bytes) corresponds to a line Oil the CRT (only the first BO bytes of each record are in the display window). The first record of the file corresponds to the first I ine of the CRT on I y if tt,e CRT has not been

This is the stand alone rom addition to the Xerox 820-11 monitor. It is called once during monitor restart and at that time patches the monitor in ram to call the modified k/b,crt,Screenprlnt and printer routines. It then moves in its own SIGNON overlay and jumps into it.

This SIGNON in addition to selecting the disk driver also moves into ram (in the spare driver area) trans laUon tables and code for k/b and printer routines (crt Is run out of rom).

Ther~ is also a RX BOOT overlay which is selected instead of the Xerox one. This loads the national translation ta~les from disk and then Calls the Xerox BOOT.

;; k/b interrupt handler for the low profile position encoded k/b. The interrupt interrupt service routine inputs two or three bytes from the keyboard port. The first byte is the cmd/status byte. Appropriate information Is saved in memory and the return from interrupt code i5 invoked. The 5econd and third byte(mouse) i5 position encoded data or mOU5e di5placement is analyzed, translated, and return to the existing keyboard handler if the information i5 valid; otherwi5e it is truncated and a return from interrupt i5 invoked. All registers saved except for the A regi5ter.
